Kevin I should probably start off with the tires as to why I chose these hubs, but you’ll see them below. The tires are an OLD Pro-Line V-Tread (no clue on their original name), but they were for the RC10 and older Tamiyas that used a 1.5″ wheel. So, my challenge was to find a small diameter wheel, and a way to attach it to a 1/4″ axle. I came up with these.. they are clamping wheel hubs for the Tamiya F104 Formula 1 car. I got these on ebay, shipped from Japan.
They clamp onto the axle.
Here is a side shot of the tires. You’re best bet if you are looking for these is ebay and r/c forums.
These are F104 rear wheels.
The wheels are a little taller than 1.5″ but the tires fit on them with minimal effort.
Here you’ll see the back of the F104 wheels. They use a 12mm hex.
The hub on the axle.
The clamping hubs didn’t quite “clamp” as tight as I’d like, so AJS Machine went the extra step and drilled and tapped 4-40 holes for set screws to help secure the hubs to the axle.
Some shots with the tires/hubs mounts. These things look AWESOME on here.

Very nice Kevin. Puller looks awesome. Good luck this weekend!
So where are you guys attaching the sled to the diggers? I pull and think this would be an awesome cheap class to start. I have prob 4 of these chassis already. Thanks
We just use the wheelie bar. I still need to cut out the spot in the body for access though.
The spur gear hub you can get from outlawhobbies.com and I believe servocity.com
Are there other wheels and tires there using like a tlt wheel and tire? Sorry for all the questions but I think this would be a good class to add to ours . Just doing some homework before I suggest us adding this class.
